pinctrl: ocelot: fix confops resource index

Prior to commit ad96111e ("pinctrl: ocelot: combine get resource and
ioremap into single call") the resource index was 1, now it is 0. But 0
is the base region for the pinctrl block. Fix it.
I noticed this because there was an error that the memory region was
ioremapped twice.
